2 Parameters
2.2 List of parameters
Description: Sets the signal source for the offset angle dependent on a thyristor pair between the line zero crossings at the power
unit and the synchronizing voltage.
Index: [0] = Thyristor pair 1-6 (UV+)
[1] = Thyristor pair 1-2 (WU-)
[2] = Thyristor pair 2-3 (VW+)
[3] = Thyristor pair 3-4 (UV-)
[4] = Thyristor pair 4-5 (WU+)
[5] = Thyristor pair 5-6 (VW-)
Dependency: Refer to: p51845, p51846
Description: Sets the configuration for the armature current actual value sensing.
Value = 0:
The device-internal armature current actual value sensing is active.
Value > 0:
An external armature currrent actual value sensing is fed to the SINAMICS DC MASTER via an analog input. The
device-internal armature current actual value sensing is not active.
Value: 0: Ia sensing internal
1: Sensing via analog input 3 (X177.1/2)
2: Sensing via analog input 4 (X177.3/4)
3: Sensing via analog input 5 (X177.5/6)
4: Sensing via analog input 6 (X177.7/8)
Dependency: Refer to: p51823, p51824
Danger: For value > 0, the following applies:
Incorrect setting of parameter p51853 leads to damaging or destruction of the power unit!
Note: For value > 0, the following applies:
This is to be used only in certain special cases, where the accuracy of the device-internal armature current actual
value sensing is regarded as insufficient.
The following applies for the Control Module:
p51852 = 0: p51824 is active
p51852 > 0: p51824 is not active
Description: Sets the voltage for the external current actual value sensing.
This voltage is supplied via the input terminal X177:x/x at armature rated current.
